Summary: This work presents a novel tubular g-C3N4 with a hierarchical core-shell structure achieved through the incorporation of phosphorous elements and nitrogen vacancies. The core is composed of randomly stacked ultra-thin nanosheets, enabling efficient electron/hole separation and visible-light absorption. This photocatalyst demonstrates outstanding performance in the photodegradation of rhodamine B and tetracycline hydrochloride under low intensity visible light, as well as remarkable hydrogen evolution rate under visible light. The introduction of phytic acid into the melamine and urea solution during hydrothermal treatment leads to the formation of this hierarchical structure, offering a facile and scalable approach for mass production.

Summary: Heteroatom doping is an efficient method to modify the electronic properties of carbon for better lithium storage capacity. Here, we report a straightforward approach to synthesize selenium-decorated honeycomb-like g-C3N4 (Se-H-g-C3N4) for the anode of a Li-ion battery. The Se doping significantly widened the gap between carbon sheets, providing more active sites for Li-ion storage and enhancing the diffusion rate. As a result, Se-H-g-C3N4 outperformed bulk g-C3N4 and honeycomb-like g-C3N4 (H-g-C3N4) in terms of rate capability and specific capacity.

Summary: Water redistribution has a profound impact on the function of dryland ecosystems. Biological soil crusts (BSCs or biocrusts), which cover a large portion of arid land soil surface, have conflicting effects on water redistribution at a regional scale. This study clarified the effects of different biocrusts on soil hydraulic properties in the Tengger Desert. The results showed that biocrusts significantly altered soil hydraulic properties, including water holding capacity, soil hydrophobicity, water sorptivity, and unsaturated hydraulic conductivity. Understanding the role of biocrusts in hydraulic properties can help improve our understanding of soil water distribution, movement, and retention in the area.

Summary: Polymeric carbon nitrides, especially the crystalline allotrope known as poly(triazine imide) (PTI), have been found to have great potential for photocatalytic CO2 reduction. However, the poor visible light absorption of pristine PTI significantly hinders its photocatalytic performance. In this study, crystalline carbon nitride nanosheets composed of PTI and melon phase junctions were synthesized via one-pot polycondensation and modified with CdS nanoparticles to create CCN/CdS hybrids with double-junction structures. The resulting CCN/CdS heterostructures demonstrated broad visible-light harvesting, enhanced CO2 adsorption/activation, and improved separation and transfer of photoinduced charges. Thus, the optimized CCN/CdS hybrid exhibited remarkable activity and high stability for photocatalytic CO2-to-CO conversion.

Summary: A new perfect triangular lattice antiferromagnet K2Ni(SeO3)(2) has been synthesized, in which both in-plane and inter-plane geometric frustration is present. The compound shows antiferromagnetic order at T(N) ≈ 7 K. High-field magnetization and electron spin resonance indicate the presence of easy-plane anisotropy. Density functional theory calculations confirm the excellent two-dimensionality of the compound. Thus, K2Ni(SeO3)(2) is a perfect triangular-lattice antiferromagnet with strong frustration and easy-plane anisotropy.

Summary: Through a systematic review and meta-analysis of 37 cohort studies, it was found that an increased consumption of sugar-sweetened beverages (SSBs) per 250 mL/day was associated with a higher risk of breast, colorectal, biliary tract, and prostate cancer. Increased consumption of artificially sweetened beverages (ASBs) per 250 mL/day was associated with a higher risk of leukemia. Increased consumption of 100% fruit juice per 250 mL/day was associated with a higher risk of overall cancer, melanoma, squamous cell carcinoma, and thyroid cancer. There were linear dose-response associations between SSBs consumption and breast and kidney cancer, and between ASBs and fruit juices consumption and pancreatic cancer.

Summary: High-grade gliomas remain difficult to treat despite standard therapy. Charged particle beams, especially carbon ion beams, have the potential to improve treatment outcomes. This systematic review assessed the safety, efficacy, and dosimetry of carbon-ion or proton radiotherapy for high-grade gliomas. The analysis of eleven eligible articles showed that charged particle radiotherapy was effective with manageable side effects. Carbon ion boost appeared to be superior to proton boost, but dose-escalation using proton boost was associated with severe brain necrosis. Further randomized control trials are needed, along with systemic therapeutic options.

Summary: The CYP76 subfamily, which belongs to the CYP superfamily, is crucial for phytohormone biosynthesis and response to environmental stresses in plants. Genome-wide analysis of the CYP76 subfamily in seven AA genome species revealed three groups, with Group 1 having the largest number of members. Analysis of cis-acting elements showed a high number of elements related to jasmonic acid and light response. Gene duplication analysis indicated expansion mainly through SD/WGD and tandem forms, with strong purifying selection during evolution. Expression pattern analysis showed that OsCYP76s exhibit restricted expression patterns in leaves and roots. qRT-PCR analysis of CYP76s under abiotic stresses revealed specific response patterns and functional divergence between japonica and indica rice. These findings provide valuable insights into the functional diversity and evolution of the CYP76 subfamily and have implications for improving stress tolerance and agronomic traits in rice.

Summary: In this study, the squeeze flow behavior of an upper convected Maxwell fluid between two rigid disks or spheres was investigated. It was found that the velocity field of the Maxwell squeeze flow between two disks is similar to that of a Newtonian fluid when the Deborah number is low. Based on the Newtonian fluid velocity field, the pressure distribution between two parallel disks was analyzed, and a theoretical model of normal squeeze force was developed. The same method was also used to analyze the interaction between two nearly contacting, arbitrary rigid spheres. Analytical expressions for the pressure distribution and normal squeeze force were obtained, which can be used in the contact model for discrete element simulation of wet particle systems with the Maxwell fluid.
